[0036] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0037] This utility model embodiment provides a telescopic winding data cable module, such as Figures 1 to 8 As shown, the telescopic winding data cable module includes a housing 1, a rotating base 2, a data cable 3, a first circuit board 4, and a second circuit board 5. The rotating base 2 is rotatably installed inside the housing 1, the first circuit board 4 is installed on the rotating base 2, the data cable 3 is wound on the rotating base 2 and electrically connected to the first circuit board 4, and the second circuit board 5 is installed inside the housing 1 and is arranged opposite to the first circuit board 4.

[0038] Both the first circuit board 4 and the second circuit board 5 have an annular conductive line 41 on one and an electrical connector 51 on the other. The electrical connector 51 has a first electrical connecting arm 511 and a second electrical connecting arm 512. The first electrical connecting arm 511 and the second electrical connecting arm 512 of the same electrical connector 51 abut against the same annular conductive line 41 to electrically connect the first circuit board 4 and the second circuit board 5.

[0039] This utility model discloses a telescopic winding data cable module. One of the first circuit board 4 and the second circuit board 5 has a ring-shaped conductive line 41, and the other has an electrical connector 51. The electrical connector 51 has a first electrical connecting arm 511 and a second electrical connecting arm 512. The first and second electrical connecting arms 511 of the same electrical connector 51 abut against the same ring-shaped conductive line 41, thereby electrically connecting the first circuit board 4 and the second circuit board 5. In this way, one electrical connector 51 provides two electrical connection points with the same ring-shaped conductive line 41 through the first and second electrical connecting arms 511 and 512, improving the electrical connection stability between the first circuit board 4 and the second circuit board 5, and enhancing the load-bearing capacity for high-power applications, making it more suitable for high-power usage scenarios.

[0040] Specifically, when the data cable 3 is stretched or wound onto the rotating base 2, the stretching or winding of the data cable 3 causes the rotating base 2 to rotate, thereby causing the first circuit board 4 mounted on the rotating base 2 to rotate, while the second circuit board 5 remains stationary. During the rotation of the first circuit board 4, the first electrical connection arm 511 and the second electrical connection arm 512 will always abut against the annular conductive line 41, thereby maintaining the electrical connection between the first circuit board 4 and the second circuit board 5. The first electrical connection arm 511 and the second electrical connection arm 512 slide relative to the annular conductive line 41.

[0041] Regarding the specific arrangement of the ring-shaped conductive line 41 and the electrical connector 51, in one embodiment, the ring-shaped conductive line 41 is disposed on the first circuit board 4, and the electrical connector 51 is disposed on the second circuit board 5. In another embodiment, the ring-shaped conductive line 41 is disposed on the second circuit board 5, and the electrical connector 51 is disposed on the first circuit board 4. Preferably, as shown... Figure 6 and Figure 7 As shown, the annular conductive line 41 of the telescopic winding data cable module of this utility model is disposed on the first circuit board 4, and the electrical connector 51 is disposed on the second circuit board 5. For the installation of the data cable 3, a winding disc 22 is disposed on the rotating base 2, and the data cable 3 is wound on the winding disc 22.

[0042] Optionally, such as Figure 8 and Figure 9 As shown, the electrical connector 51 further includes a mounting section 5111, and the first electrical connecting arm 511 and the second electrical connecting arm 512 further include a connecting section 5112 and an abutment section 5113. The mounting section 5111 is mounted on the first circuit board 4 or the second circuit board 5. The connecting section 5112 of the first electrical connecting arm 511 and the second electrical connecting arm 512 is respectively connected to both ends of the mounting section 5111, and the abutment section 5113 is connected to the connecting section 5112. The abutment section 5113 of the first electrical connecting arm 511 and the second electrical connecting arm 512 provides two contact points with the annular conductive line 41. The design of the connecting section 5112 allows the abutment section 5113 to make more stable contact with the annular conductive line 41 and enables the electrical connector 51 to be installed stably.

[0043] Optionally, the end of the connecting segment 5112 furthest from the mounting segment 5111 is raised, and the abutting segment 5113 is U-shaped, with its opening facing away from the annular conductive line 41. The raised end of the connecting segment 5112 furthest from the mounting segment 5111 gives the electrical connector 51 an overall "arch" shape, providing structural elasticity and buffering when the abutting segment 5113 contacts the annular conductive line 41. The U-shaped structure of the abutting segment 5113 allows for better contact with the annular conductive line 41, forming a stable contact point. In another embodiment, such as... Figure 12 As shown, the mounting section 5111 and the connecting section 5112 are connected by the extension support 5114. The extension support extends toward the first circuit board 4 of 5114 to increase the contact stability between the abutting section 5113 and the annular conductive line 41.

[0044] The abutment section 5113 includes a straight abutment portion 51131 that abuts against the annular conductive line 41. In this embodiment, the abutment section 5113 includes a straight abutment portion 51131 that directly contacts the annular conductive line 41. The straight design makes the contact between the abutment portion 51131 and the annular conductive line 41 more uniform and stable. Specifically, the straight abutment portion 51131 can provide stable electrical contact, reducing signal transmission interruption or power loss problems caused by poor contact. This design is particularly suitable for high-precision and high-power applications. Furthermore, because the contact between the abutment portion 51131 and the annular conductive line 41 is straight, the straight abutment portion 51131 can evenly distribute pressure on the annular conductive line 41, reducing the possibility of localized excessive wear. This uniform pressure distribution can effectively extend the service life of the annular conductive line 41 and the electrical connector 51. In another embodiment, such as... Figure 11 As shown, the abutment section 5113 is U-shaped with an overall arc shape.

[0045] Furthermore, insertion portions 51111 are provided on both sides of the mounting section 5111, and these insertion portions 51111 are inserted into the first circuit board 4 or the second circuit board 5. These insertion portions 51111 can be inserted into corresponding holes or slots on the first circuit board 4 or the second circuit board 5 to achieve fixed installation of the electrical connector 51. The insertion portions 51111 are further soldered onto the first circuit board 4 or the second circuit board 5. By providing insertion portions 51111 on both sides of the mounting section 5111, the electrical connector 51 can be firmly fixed to the first circuit board 4 or the second circuit board 5. This design can effectively prevent the electrical connector 51 from loosening or shifting due to mechanical vibration or external force during use, reducing contact problems caused by loose electrical connector 51, thereby improving the reliability of the electrical connection.

[0046] Furthermore, such as Figure 7 As shown, multiple ring-shaped conductive lines 41 are provided, with the same center but different radii; each ring-shaped conductive line 41 corresponds to at least one electrical connector 51. The multiple ring-shaped conductive lines 41, with the same center but different radii, can realize the transmission of multiple signals or power. Each ring-shaped conductive line 41 corresponds to at least one electrical connector 51, ensuring that each ring-shaped conductive line 41 can achieve a stable electrical connection. The multiple ring-shaped conductive lines 41 and electrical connectors 51 can be used to transmit power and data signals, etc., and can be configured according to specific needs, which will not be elaborated further here.

[0047] Furthermore, each annular conductive line 41 is provided with at least two electrical connectors 51. Providing at least two electrical connectors 51 for each annular conductive line 41 allows for multiple contact points, reducing electrical connection interruptions caused by poor contact at a single point. Specifically, there are six annular conductive lines 41, each with two corresponding electrical connectors 51. In this case, each annular conductive line 41 has four connection points with the electrical connectors 51. Specifically, the number of electrical connectors 51 can be increased or decreased according to actual application conditions to control the number of contact points and provide a more reliable electrical connection. For example, the corresponding electrical connectors 51 of a single electrical connection function module can be set in groups, with six electrical connectors 51 forming one group; one group or two groups can be set.

[0048] On the other hand, such as Figure 3 As shown, the rotating base 2 has a mounting cavity 21, within which a coil spring 6 is installed. When the data cable 3 is stretched, the coil spring 6 winds up and stores energy. The rotating base 2 has a mounting cavity 21 for mounting the coil spring 6. The coil spring 6 is installed within the mounting cavity 21. When the data cable 3 is stretched, the coil spring 6 winds up and stores energy; when the data cable 3 is released, the coil spring 6 releases energy, causing the rotating base 2 to wind the data cable 3 back. The rotating base 2 also has a positioning mechanism. When the user stops stretching the data cable 3, the positioning mechanism positions the rotating base 2, keeping the data cable 3 at its current stretched length. If the user pulls the data cable 3 slightly again, the positioning mechanism releases the lock on the rotating base 2, and the rotating base 2 rotates to wind up the data cable 3 under the drive of the coil spring 6. The specific installation of the coil spring 6 and the specific implementation of the positioning mechanism can be achieved using existing conventional methods, and will not be described in detail here.

[0049] Furthermore, such as Figure 1 As shown, the housing 1 includes a first base shell 11 and a second base shell 12, which are mounted together. The first base shell 11 and the second base shell 12 have cable outlets 13 on their sides, from which one end of the data cable 3 is led out. A second circuit board 5 is mounted in the first base shell 11. A window 111 is opened on the side of the first base shell 11 facing away from the second base shell 12, and the power-on pins 52 of the second circuit board 5 are correspondingly arranged in the window 111. By dividing the housing 1 into a first base shell 11 and a second base shell 12, this modular design makes the assembly process simpler and more efficient. The first base shell 11 and the second base shell 12 can be processed and assembled independently, and then mounted together, reducing the complexity and error rate in the assembly process. The cable outlet 13 on the side allows the data cable 3 to be smoothly led out from the module. The window 111 on the first base shell 11 corresponds to the power-on pins 52 of the second circuit board 5, facilitating connection to external devices.

[0050] Furthermore, such as Figure 4As shown, the first base shell 11 is provided with multiple limiting baffles 112. These baffles 112 pass through the second circuit board 5 and are engaged on the side of the connection section 5112 between the first electrical connecting arm 511 and the second electrical connecting arm 512. The limiting baffles 112 not only improve the installation firmness of the second circuit board 5 but also enhance the installation stability of the electrical connector 51, preventing loosening during sliding. The first base shell 11 also contains a rotating mounting post 113. The rotating base 2 is rotatably mounted on the rotating mounting post 113, and the second base shell 12 is mounted on the rotating mounting post 113 by screws.

[0051] This utility model also discloses an electronic product with a telescopic data cable module, including the aforementioned telescopic data cable module. The electronic product can be a telescopic data cable 3, a power adapter using the telescopic data cable 3, a power bank, a power strip, or other electronic products.
